WASHING HAGHINE.

; Application filed July 25, 1923. Serial No. 658,895.

To all whom it may concern:

Be it known that I, Nroom MAs'rno- MARIDNO, a citizen of the United States re ful improvement in washing machines. The

object of the invention is to provide a washing machine of simple construction that may be readily connectedup with any suitable source of water supply for furnishin water eating the water when desired. Another object of the invention is to mount the machine in a cabinet; which may be readily moved about to any location desired without disturbance of the mechanism and so constructed that it may be readily connected up with driving mechanism, water supply and source of heat. Another object of the invention is to provide means whereby the clothes after being washed may be squeezed to press the water out of them in the same receptacle in which they are washed. Other objects of the invention will be more fully set forth hereinafter.

One feature of the invention consists in providin a rotary drum whichserves as a tub in w ich the clothes are tumbled while being washed and mounted in a water tank;

.the drum being apertured in such manner that water will freely circulate through the drum during the rotation of the drum.

Another feature of the invention consists in providing a movable partition in the drum which may be opened so as to make the two compartments into one in which the clothes are tumbled during the washing operation and'which may be closed at will to divide the drum into two compartments when the rotation of the drum is stopped, one of which will contain the clothes. The drum may be turned so that the compartment containing the clothes will be at the top, the clothes then resting on the partitionas a bottom while the water drains through the partition into the lower compartment of the 1:lrum and out through the drum into the tan Another feature of the invention consists in providing a presser member located in that compartment ofthe drum in which the clothes will be located when the partition is closed and means for actuating said presser member to squeeze the waterout of the clothes. Another feature of the invention consists in providing a movable cabinet case for the apparatus to entirely enclose the same when desired and in which the mecha- 4 nism is mounted, said cabinet having suitable fittings for detachable connection with a water faucet, the source of energy for supplying heat and for connection with motive ower.

0t er features of the invention will be more particularly described hereinafter and claimed at the close of the specification. The invention will be fully understood from the following .description when taken in connection with the accompanying draw- 7 ings, and the novel features thereof will be pointed out and clearly defined in the claims at the closeof this specification.

Referring now to the drawings:

There is shown at l a metal water tank 7 which as shown in the drawings is of reotangular contour enclosed in a cabinet 2.

The cabinet is preferably provided with legs 4 atthe corners, said legs having casters 5 to enable it to be easily rolled about on the floor to position it wherever desired.

The tank is provided with a water inlet opening in one of its walls near the upper es in the upper, coman showing a portion of sink or other suitable source of water supply, not shown. The cabinet will also be gas fixture, not shown.. Any other suitable heating, device, however, may be employed.

The wash tub consists of a rotary drum 12, preferablyof cylindrical form and made of metal, said drum having the two ends or heads 13, 14 and peripheral wall 15. The heads of the drum are provided with trunnions 16, 16, said trunnions being journaled in bearin in the upright leg portions 17, 17 of a -shaped frame having a base portion 18 connected to the upright portions, said base resting onthe bottom of the tank. The leg 17 y is shorter than the leg-17*, the bearing for the shaft in that leg being a U-shaped recess in the top of the leg so that the shaft can be dropped therein from above to enable the shaft to be mounted in the bearings.

The drum is revolvable on its trunnions within the tank. The periphery of the drum is formed with a large number of apertures I 22 in its perip each other through either one of whlch the clothes may be introduced into the tub or 19 so that as the drum revolves and the apertures come below the water'level in the tank, thewater will. freely circulate through the said apertures into the drum and thereby maintain a water level in the drum, the same as thewater in the tank. The proper water level is shown at 20 slightly below the central axis of the drum. The drum is rovided with two doors 21, liery diametrically opposite drum, according. to whichever is onthe .upper side. They will be removed through the door '21 as will be hereinafter described.

When. the clothes are to be introduced into thedrum the drum will be adjusted so as to bring either the door 21 or the door 22 to I the top. In the drawings thedoor 21 is at the top. When the clothes are to be removed after the washing and squeezing the drum will be stopped after the rotation at a time when the door 21 will be at the top. These doors are preferably hinged as at 23 and are provided with a catch 24 for fasten-' ing them in closed osition. There are also provided meansor securing the drum against rotation when it isv desired to stop it either in the position for introduoin the clothes or for taking them out. As s own in the drawings the periphery of the drum is provided with two loops 26, 27 at diamet- 1,,iea

the trunnions said gear wheel having driving connections with suitable driving means. As shown in the drawings said gear wheel is a bevel gear and engages with a bevel pinion 30 mounted on a shaft 31 journalled in suitable bearings 32, 32, the other end of said shaft being provided with a bevel pinion 33 which engages with a bevel gear 34 mounted on a shaft35, said shaft 35 carrying a sprocket wheel 36 which has a sprocket chain connection 37 with a sprocket 38 mounted on a shaft 39 and which in turn has driving connection with a shaft 40 of a motor 41 by means of a sproket 42, chain 43, a sprocket 44 mounted on ashaft 45 carrying a sprocket 46 over which runs a chain 47 which also runs over the sprocket 48 on.

the motor shaft 40 v Any other suitable form of driving connection, however, may be employed for driving the bevel gear 31. While the means for driving said shaft as shown in the drawings consists of an electric motor, any other kind of motive power may be employed.

In orderto protect the gears both from the water and from outside interference, the cabinet is extended both at the back side and at one end' and a partition 4 is provided on the back side to form a chamber 50 for the gears and shafting on the back side, and a partition 51 is provided at the end to form an end chamber 52 to enclose the gears and driving connections at that end.

The drum is provided with a movablepartition which extends from end to end of the drum so that the drum may be divided, when desired, into two compartments. In the form of construction shown, this partition is of a roller type, preferably formed in two parts 53, 53 which slide in opposite directions. Each member of the partition is preferably composed of rollers 54 laid parallel with each other and connected by links 55 in such manner that the partition agh st r manipulating the partitions. open 1 and shown at the top in Figs.

'- transversely ofthe drum slightly arched of said shells is of slightly allow tor the over the center of the drum. In order to roper construction of the run-way the penpheral wall of the drum is formed of two semi-cylindrical shells. One less diameter than the other, the shell which is connected with that portion ofthe head in which the the semi-circular portion of the run-way is formed being of the less diameter, the lower of the other shell which is the upper shell, when the drum is in the position shown in Figs. 1 and 3, slightly overhanging the lower shell.

This allows free clearance for the run-way and makes a thin spacev 61 between the lower edge of the upper shell and the upper edge of the lower shell when inthe position shown in said figures.

When the said roller partitions are turned down into the positions shown in Fig. 1, the

interior of the drum is all one compartment. 7

This is the position that the partition should occupy preliminary to the introduction of the clothes for the purpose of washing. The cabinet is provided with a hinged cover 62 which should be kept closed except when the machine is about to be used.

A movable partition plate 63 of segmental form is mounted upon a feed screw 64 which extends longitudinally of the drum and has its ends journalled at 65- and 66. This plate is in a plane at right angles to the axis of rotation of the drum. The convex edge 67 of said partition lat/e follows the inner periphery of that s ell of the drum which does not contain the. roller partition and the concaved edge of said partition follows the curve of the upper edge of the flange 58 of the run-way, as shown in Figs. 1 and 3. One end 68 of the feed screw ca is squared to receive a wrench and extends into the space between the end wall of the drum and the end of the tank. A hole 69 is formed through the wall of the tank in alinement with the said feed screw for the introduction of a socket wrench to engage with the squared end 68 of the feed scriefy to rotate said feed screw when desired.

strengt ening rib 70 having at its outer end .a lu 71 which is tapped out for the passage screw the said partition plate axis of the plate 63 is preferably .formed with a the cover 62 will be fhfiwnopelrthen the door 21 or'22 of the drum will be opened,

the hook 28 being engaged with the loop on the drum to prevent rotation.. The clothes 72 will be introduced into the drum through said door 21 or '22'and .will fall to the bot- .tom of the drum. At this .time the partition 63 should be in the position shown in dotted lines in Fi 2; that is at the extreme end of the drum, t e ehtire drum being now one compartment. Water will be admitted the re r level.

T e rum will then be rotated either by starting up the motor or by whatever means are employed for rotating the drum and the clothes willbe tumbled about in the drum,

the water having free circulation from the tank through the drum as already described- The rollers 54 which make up the roller partition are cylindrical rods which extend the through the pipe 6 and the tank filled to Whole length of the drum next to the inner periphery thereof and these will aid in tumbling the clothes. When the drum has been rotated a suficient number of times to give the clothes the proper amount of washing, the rotation of the drum will be discontinued when the drum is in the position shown diametrically opposite that shown in- Figs. land 3. The flattened portion of the run-way will then be on the underside. The operator should then grasp the handles 60 of the two members of the roller partition and move the two partition members into closed position. The clothes being in the then underside 'of the drum will be pushed down by the pressure of the said roller partition and be retained in that compartment of the drum. There should never be enough clothes in the machine at any one time to make the drum too full for this purpose.

the squared end 68 of the feed screw and the feed screw should be turned in a. direction to move the presser plate 63 from the dottedlme position shown in Fig. 2, at one end of the drum toward the opposite end as shown by the full-line position in Fig. 2. This will squeeze the clothes a inst the opposite end of the drum an the water will drip through the spaces between the rods of the roller partition into the lower art of the drum and thence into the tank. An outlet pipe 73 is provided in the lower art of the tank which should be opened to raw 0d the water. The tank is preferably formed with a sloping channel 74 in the bottom to carry the water toward the drain outlet.

' When the clothes are sufliciently squeezed I when washed maybe assembled in one of said compartments, a movable presser member located in the compartment in which the clothes are assembled and means for moving said presser member to push the clothes toward one end of said compartment and squeeze them.

2. A washing machine having a water tank, a rotary drum mounted within said tank, a door for admission of clothes into the drum and for removal therefrom, a roller partition within the drum which may be adjusted to divide the drum into two compartments or moved back to make the said two compartments into one, a presser member located in one of said compartmentsand means for operating said presser member to squeeze the clothes in said compartment.

3. A washing machine having a rotary drum for washing and tumbling the clothes, said drum being apertured' to permit the circulation of water into and out of the drum, a movable artition member which is movable at the wiil of the operator to divide said drum lon 'tudinally into two compartments lengthwise of the drum, and a movable presser member located in one of said M two compartments and movable toward one clothes and of the heads of the drum to squeeze the 4. A washing machine having a water a tank, a rotary drum mounted within said tank, a door withinthe wall of the drum to permit the introduction and removal of the articles to be washed, the drum being apertured to permit water from the tank to freely pass in and out of the drum a roller partition which may at will be-adJuSted to divide the vdrum longitudinally into two compartments or rolled back to make the member located in one of said compartments" which is movable parallel with the axis of,
